Tottenham Hotspur manager Jose Mourinho has said former Arsenal chief Arsene Wenger was the last of his kind among coaches, suggesting the days are gone when the same tactician leads a team for decades.
The rate of managerial turnover in world football has steadily increased in recent years. Wenger withstood criticism throughout his final years at Arsenal and finally ended his 22-year reign at the club in 2018.
Sir Alex Ferguson holds the record for longest-serving Premier League manager after he served Manchester United for 27 years, while Mourinho failed to make it three years in the job at Old Trafford.
